Referring by numerals to the accompanying drawings which illustrate a practical embodiment of my invention, 10 designates ahorizontally disposed plate or table which is supported; at a suitable elevation, preferably by means of legs 11 or a suitable frameof the but work, and fixed to said table. and project,-

ing upwardly therefrom, is a casting 12 which forms the mainsupportingframe for the operating parts of themachine. This casting is provided with various bearings, supporting armsand brackets whichare hereina'ftermore specifically described. An

wardly projecting portion 13 at the front'of this casting 12 serves as an anvil and work support, the upper face of said anvil being provided with a pair of alined transversely disposed grooves 1a which receive the ends of the staple after the same is formed and guides said ends upwardly to clench the work. (See Fig. 6.) i

Formed in casting 12 immediately to the rear of the anvil 13 are bearings "15, the same being spaced apart a suitable distance and serving as supports for the endof a horiwhich serve as a support for the ends of a transversely disposed shaft 19, and formed integral with and projecting outwardly from the casting adjacent to'the righthand one of these hearings is a horizontally disposed bracket 20, the same serving as a support for a spool 21 of wire, and which latter isfed to the machine and formed into button attaching staples. V

Formed integral with the casting adjacent the lefthand one of bearings 18 is an upwardly projecting bracket or standard 22 which serves a support for the button chute. Formed integral with the rear portion of the casting 12 and projecting upwardly therefrom is a pair of arms or brackets 23, the upper ends thereof being provided with bearings for a horizontally disposed shaft 2 1. These arms 23 also serve as a support for the button container, hereinafter more fully described. I Arranged between the lower portions of arms 23 is a vertically disposed bearing 25 and arranged to move freely therethrough is a rack bar 26. Pivotally connected to the lower end of this rack bar: is the upper end of a connecting rod 27, the lower end of the latter being pivotally connected to the rear portion of a pedal lever 28, the rear end of the latter being pivotally connected to. the lower portion. of the supporting framework for table 10. Connected to this lever 28 in front of the connecting rod 27 is the lower end of a retractilepspring 29, the upper end of which is connected to a suitable part of the supporting framework 11 and said spring normally holding the forward end of lever 28 in elevated position. Loosely mounted on shaft 19 is a mutilated pinion 30, the teeth of which mesh with the teeth of rack 26 and formed integral with or fixed to the right hand side face of said pinion is an outwardly projecting flange 31 the outer face of which is in clined relative to a vertical plane. Formed pression spring 38.

Loosely seated inone of the teeth of pinion 30 and at the end of the elongated opening or space between said teeth is a pin 36 provided on one'end with a head 37 and interposed between this headand the tooth in which said pin is seated is a com- This spring-held pin perform thefunctions of a yielding tooth in a manner hereinafter more fully described. Y

Loosely mounted on shaft 16 is a pair of segmental plates 39, the samebeing rigidly connected near their outer edges by a trans- One of these plates is provided With a series of teeth 11 V which mesh with the teeth of pinion 3Q. Formed in the front faces oftheplates 39 and near their outer edges are alined horizontally disposed wire receiving notches 12 and formed. on the inner ora'djacent faces of said plates 39 and leading upwardly from these notches 42 are grooves 13 which latter receive the legs of the staple after the same has been formed. (See Fig. 5).

Seated in the rear portion of thelefthand one of plates 39 is an outwardly projecting pin 14: and pivotally arranged on the outer end thereof a horizontally disposed spring-held detent45, the same being provided on its forward end with hook 4:6. Loosely arranged between plates is a plate 17 in which is formed a slot 18 through which shaft 16 passes, and formed on the lower portion of this plate is a series of teeth 49 which are adapted to engage with the teeth of mutilated pinion 32.

One end of a'retractile spring'50 is scopposite end of said spring being secured to the lower portion of casting 12. "Projecting outwardly from the lefthand side of the ing 25 is a forwardly projecting arm 52 in the forward end of which is formed a substantially. inverted L-shaped slot 53, which slot receives pin 51.. V

Interposed between the base of casting 12 and the forward end of this arm 53 is a compression 'spring 54: which normally maintains the forward end of arm 52 in an elevatedposition with pin 51 occupying the lower end of the vertical leg of slot 53.

(See Figa12), r

The arm 52 lies immediately beneath disk 33 and formed on the upper edge of said arm is an upwardly presented lug 55 which is adapted to be engaged by'the lugs 34. and

on said disk 33, andtormed in said arm immediately in front of thislug is a recess56.' I e Formed integral withthe upper "portion of plate 27 is an upwardly projecting lug 57 which performs the functions ofa hammer or pressure member to force the staple through the work and tocause the legs of said staple to clench againstthe underside of the work by reason of contact of the alined horizontally disposed groovesp' 59 which are adapted to coincide with grooves l2 in plates 39 when the staple is being forced through and clenched upon the work. Formed in the upper rear corner of thelug 57 is a button e e-receivingnotch 60, the same being intersected by a transversely disposed wire receiving aperture 61. f

Removably positioned "on standard '22 is an inclined chute 62 of suflicient sizeto receive the bodies of ordinary shoe buttons, and formed in the bottom-oi this chute is a longitudinally disposed slot through which the eyes of thebuttons project, The slotted bottom of this chute extends downwardly and outwardlyand terminates at a point immediately above the path of travel of the upper edges of plates 39 and the outer end of hammer57. (SeeFig. 7 Secured to the lower end oi? chute 62' and projecting downwardly over a part of-the projecting bottomot' said chute'isa relatively light spring 6 h the forward end of which is curved downwardly and said spring serving as a yielding finger for controllingthe feed or movement oithe rowjot 5 buttons downwardly tl'lrough the chute and onto the'outer end of the lower portion of said chute and in which latter position the buttons-are suc cessively engaged by the end oi' hammer 57.

a longitudinally The means utilized for transferringthec lowermost one of the buttons within the chute from its position behindnthe curved outer end. or spring 64 to the extreme outer end of the lower portion of said chute in cludes a plate pu'ovided. with :slot 66 which receives shaft lliand secured to the lower end of this .plate'is one end of a re tractile spring 67, the opposite end ot' which is secured to the lower portionotcasting l2; This spring norn'ially acts todraw the plate 65 downward and in such position theshai t 1 6 occupies the upper endot' slot-66; l- Proje'cting upwardly from the rear portionof plate 65' is an angular arm 68,;a part of: the

upper portion of which" is bentlaterally as designatedby 69 andsaid laterally bent portion overlying the lefthand "one" of plates 39. This laterally bent po'rtion'terminates in a depending button engaging hook 70;the same being provided with a curved lower edge, and this hook operates through the lower portion of the slot 64 inthe spring 64;.

Formed on the rear upper edge ofplate 65 is an outwardly projecting flange '71 which is adapted to be engaged by thehook 46 on the end of detent 45. I (See Fig. "16)..

Projecting outwardly from the lefthand side of plate 65 is a pin 7 2 and pivotally mounted upon a pin 73 which is seate'dinan adjacent part of the bracketv 17' is a relatively short dog 74:, the free end of which is normally held in depressed 'positionflby'a suitable spring 75, the same bearing upon a pin 76 which projects outwardly from I. said dog; Seated in the-lower portion of post 22-is a screw 75 against'whichtherear end of detent 45-is adapted to engage when the-latter is at its rearward limit ofmovement Under normal conditions, pin 7 2 is'pos'itioned beneath the pivoted end of the dog 74.- as illustrated in Fig. 17. This dogis' tor the purpo'seof elevating plate 65 inorder to position the hook 70 over the lowermost one of the buttons in chute 62 andtransier said button into position onthe hammer and staple forming means. I

Supported between i the upper portions of the arms isa suitable button receptacle or hopper 77, a p'ortion'78, preferably at the topcthereof, being constructed of transparent material such as} glass or celluloid,

and formed in the'front wall of this recepe tacle is an opening '29 into which extends the upper end or" button chute 62.) The but, ton chute is detachably connected to the re ceptacle in any suitablemanner, preferably by means of a pin 86 which is loosely seated recess aPerl/111e imed in a part of said receptacle; r

The parts of the slotted bottom at the chute 62 are spread apartfwithin the button receptacle tov form button guiding plates 81 and extending transversely. across the re ceptacle above'these plates'is a raillSQ, the underside of the center of which is notched as designated by '83 in order to permit the heads 'ofbuttons to enter the slot in the bottom of'the chute.

Carried by shaftQt within the receptacle 77 is an ordinary horsesshoe magnet 84, the greater portions of the legs of which are covered by a suitable shield 85 of-insulation, thereby exposing. only the ends I of the legs of said magnet. .3, J l

During operation or Ii'lOVSlIlfiIlh of the magnetl the outer ends of its legs, travel in a path immediatelybeneatli' the slot between the guiding plates Sl-and rlikewlse mime diately beneath notch 83 111 Ldefiecting bar is a pinion 87 which is engaged by the teeth of a rack bar 88, the latter being formed 'integral with or fixed to the upper end of rack bar 26.

By reason of the fact that pinion S7 is arranged outside the adjacent arm 23, the rack bar 88 is offset laterally relative to the rack bar 26.

Pivotally mounted on bracket '20 is a horizontally disposed arm 89, the outer end of which is adapted to receive the strand of staple forming wire which is carried upon spool 21, and pivotally mounted on the outer end of said arm is apivotally mounted spring-pressed wire grippingmember 90.

A coiled spring 89, one end of which is secured to the arm 89 the other end being secured to the bracket 17 is provided to control the arm'89 as hereinafter described.

Formed in the righthand one of brackets 17 is an aperture 91 through which the staple forming wire is adapted to feed, and pivotally mounted above said aperture is a spring-pressed wire gripping member 92.

(See Fig. 20.) j

The operation of my improved button setting machine is as follows: v

Under normal conditions, or with the machine ready for operation, thevarious parts occupy the positions illustrated in Figs. 1, 3 and 7, with the eye of a button occupying the notch 60 in hammer 57 and the end portion of the stapling wire seated in the notches 42 and passing through the eye of said button.

The work which is to receive the buttons the notches 42 as illustrated in Fig. 4, by a shearing action between the outer edge of the righthand one of plates 39 and adjacent edge of the righthand post or standard 17. Segmental plates continue to move forwardly' and downwardly toward the anvil during which time plate 47 remains stationary, inasmuch as mutilated pinion 32 is not yet in engagement with the teeth 49 on said plate 47, and said plate is held in its stationary position by pin 51 in the lower end of slot 53. This movement of plates 39 past stationary hammer 57 on plate 47 bends the end portions'of the severed section of wire into positions parallel with each other, thereby forming the legs of the staple and which legs occupy the grooves 43 on the inner faces of said plates 39. (See Fig. 5.) Immediately following this action, lug 34 on disk 83 engages lug 55 on arm 52, thereb swinging the free end thereof downwarc,

. with the result that the hook above slot 53 engages on top of pin 51, hearing clownwardly thereupon and immediately pulling plate 47 downward into the position as illustrated in Fig. 9, with the notch or recess 60 disengaged from the eye of the button.

After lug 34 passes lug 55 and enters notch.

rear of notches 42 and grooves 43, the latter being occupied by the legs of the staple. At this instant, the first tooth of mutilated pinion 32 engages the teeth 49 of plate 47, and the'latter is rotated upon shaft 16 independently of plates 39, with the result that the top of the staple is engaged and said staple carrying the button is forced downwardly from its position between the front edges of plates 39.

During the staple driving action, pin 51 will travel through the upper portion of slot 53, plate 42 being held in depressed position by lug 35 engaging lug 55.

The legs of the staple will be forced through the work and the ends of said legs bearing in the grooves 14 will be turned up wardlytoward each other and thereby be firmly clenched against the underside of the work. It will be understood that all of the movements just described take place in rapid succession as the lever 28 and parts connected thereto are moved downward.

After the front edges of the segmental plates 39 are brought into engagement with the upper surface of the work lying on the anvil 13, the head of pin 36 bears against the outer face of the lower one of the teeth 41 and upon the continued rotary movement of pinion 30, pin 36 will be forced through the tooth 011 which it is mounted and spring 38 will be compressed, such action being provided in order to compensate for varying thicknesses of material placed on the anvil and to which the buttons are movement gripping'member' 90 will ride over the wire passlng through the end of said swinging arm, and upon the return. movement of 13111101160, arm 89 W111 swing rack 26 imparts reverse rotary movement to pinion 30 and the various parts actuated by said pinion and the associated pinion and disk 82 will be returned to their normal positions, as illustrated in Fig. 7.

Under normal conditions, the'rear endof detent 15 bearing against screw 75 holds said detent in an inchned position, asillustrated inFig-S with'the hook 416zdisengaged from flange 71. During the forward movement of plates 39, one of which carries detent 45, the latter will swing into a position approximately parallel with the planes occupied by said plates, as illustrated in Fig. 14 and upon the return of the plates 39 to their normal positions, hook 16 will engagejfiange 71, thereby rocking plate upon the shaft 16 so as to swing the button engaging hook'70 on the upper end of said plate rearwardly or to a position to engage immediately over the lowermost oneof the buttons in the chute 62 and which button is positioned against the curved lower end of spring 64. Simultaneous with this rearward swinging movement of plate 65, said plate will be elevated by thefmovement of pin 7 6 riding overdog 74, which latter is pivoted to-a fixed part of the frame and when hook has engaged the lowermost one of the buttons, the rear end of detent 15 will come in contact with pin thereby throwing the forward end of said detent outwardly, consequently disengaging hook 16 from flange 71, and plate 65 and parts carried thereby. will instantly ride to their normal positions under the influence of spring 67, and consequently carrying the lowermost one of the buttons downwardly onto the projecting bottom portion of the j chute and with the eye of said button seated in notch 60.

During the forward swinging movement of plate 65 pin 72 will ride beneath dog 74 as illustrated in Fig. 17, consequently raising the forward end of said dog, but on the rearward movement of the plate, said pin normal positions, a button will be placed.

in proper position on the carrying means with theeye of said button: in the recess 60 and immediately. after the button is thus positioned, "arm'89 lwlll ride'ofi the flange -31 and the endlof the wire will be sfed throughx'the eye of the button, thus com.- pleting the cycle of operations As rack bar 26 is drawn downward, as 1 heretofore described, rack barSS will be 1 likewise 'drawn downward, thereby impart ingrotary movement to pinion 87 and shaft 2&1, with the result that the magnet 84 will be partially rotated within the buttoncontainer and the eyes of the buttons beingof metal will be attracted and held upon the ends ofthe legs of said magnet. As the magnet revolves in the oppositedirection within the housing, the engaged buttons with the body portions IlDPSI'HlOSl] will be moved between the curvedv plates 81 forming the upper portion of the bottom of the button chute and the heads of said buttons will :pass beneath the notch 83 ofidefleetor 82." Thus, with each upward movement of.

the rack bar, one or more buttons will be delivered in proper position into the upper end of the button chute. i' i In the event that it is desired to attach a certain size -or style of button into work such as a. pair of shoes, the button chute 62 can be readily disengaged from the button receptacleand from the support 22, and the special style of buttons may be manually fed into the upperend ofthe chute.- Thus it will be seen that I have produced a button'stapling machinewhich is composed of relatively few parts, .the'same coeperating to act positively,rapidlyand efficientlyto perform their intended functions and achieving the desired results.

1 While the various parts constituting my complete machine have been described somewhat particularly,-it will be understood that the structural details are capable ofl considerable. variation. within the spirit-and scope of the appended claims.
